conflict between "portA +python33" and "portB +python33"

[Mojca Miklavec]

Hi,

What is the most reasonable way to declare a conflict between "portA
+pythonXY" and "portB +pythonXY"? The ports themeselves don't conflict
and different python variants don't conflict either (portA +python33
and portB +python34 works OK).

The problem is that both ports install files with the same name to
$prefix/Library/Frameworks/Python.framework/Versions/X.Y/lib/pythonX.Y/site-packages
when the same python variant is selected for both ports.

Thank you,
    Mojca
